Need help writing a simple script to chown files

[john]

Thanks Jim,

By the way are your students using unix or are they using Windows and
dropping stuff to a SAMBA share? If SAMBA why did you chose the method
of preserving file ownership your mentioned rather than using some
switch in smb.conf like "force create mode ="?

I am just wondering since I have been toying with the idea of a
"dropbox" as well.

Thanks for your help!

John
